Jet Blue's air-to-ground cellular network (provided by LiveTV on the same spectrum as those in-flight phones no one uses) is still experiencing too many dropped connections between cell nodes to support the bandwidth necessary for full-on surfing, the NY Times is reporting. Hence the Yahoo Mail/IM and Blackberries only restriction, and the lack of cost. American, Virgin America, and Alaska Airlines are expected to join the fray with more robust, pay-per-use services "in the coming months," the latter using a more reliable and international satellite connection for more bandwidth and range.
